IMPROVEMENT IN MACHINES FOR PRINTING FABRICS 0F CIRCULAR FORM.

Speciicationrforming part of Letters Patent No. 176,626,- dated April 25, i876 application filed April 27, 1869.'

To all'whom it may concern Beit known that I, EMILE HARTMAN, of Brooklyn, E. D., county of Kings, State of New York, have invented a certain new and useful Machine for Printing Circular and Analogous Shapes; and I do hereby declare the followin gis afull and exact description that of the same, reference being had to the accompanying drawing, being part of this specilication.

Similar letters of reference indicate like parts 'in the several figures.

use of a conical roller, which has the Ornament to be printed engraved on its surface, anda press-roller also conical, both of such a taper that the surface to be printed', the developed surface of a truncated cone, when entered between these rollers with one of its ,radial sides, will be drawn through and be printed without drawing too much on one side or the other.

For this purpose it is necessary that the two conical rollers be constructed in such a manner that their vertexes meet iu one point, whereby any shifting of anyone point on one roller on the line of contact over the corresponding point of the other roller, causing the one point to travel faster than the other, is prevented, and a true rolling motion produced.

The printing .of suchornaments has been till now done` by blocks and by hand, but with my machine, and a number of circular surfaces 'joined by suitable means, a great saving of labor and time will be effected.

By making the printing-roller of anyV defected, any other shape than conical may be printed.

A A1 are the two side frames carrying the bearings of the printing-roller B, the pressroller C, and the ink or color roller D. A2 is the foundation-plate; A3, a cross-bar connecting the two side frames A A1 at the top.

The bearings of the press and ink rollers are constructed in such a manner as to ada-pt themselves to any form of print-roller the taper and diameter of' which will change according to the form of the circular shape to be printed, and the design on the same. For this purpose the pillow blocks or bearings E E are provided with trunnions c e',

which can travel up and down in a slot in the `side frames. By these means they areable to adapt themselves to any radial position the journals of the press-roller may occupy.

The bearings f f of the' color-rollerare constructed in the same manner as shown in the drawing.

G G are screws that force the press-roller down on the printroller with the desired pressure. El H' are screws that force the color-roller up against the print-roller. I is the colorbox. J is a pulley or gear secured to the shaft of the print-roller, giving the latter its revolving motion. K is the scraping-plate, turning on the centers lo k', and held in close contact to the surface of the printing-rollerlwreighterllelersLL' therebyremovingiallwtlmmrplus color frnniwthe A't'M -is shown the engraved design which takes up the color and transfers it to the cloth lwill vtravel fester at 'the large end of and a conical impression-roller, operating' tothe cones than :it the small, and that a circuget-her, substantially as and for the purposes lar surface will be printed. set forth.
